A simple and efficient FFT-based fast direct solver for Poisson-type equations on 3D cylindrical and spherical geometries is presented. The solver relies on the truncated Fourier series expansion,… (More)

We develop a parallel Jacobi-Davidson approach for finding a partial set of eigenpairs of large sparse polynomial eigenvalue problems with application in quantum dot simulation. A Jacobi-Davidson… (More)

In CPU-GPU hybrid systems, the QR factorization in MAGMA results in CPU idle due to the fixed block size. To improve the computational efficiency of MAGMA QR factorization, we propose a variable… (More)

A numerical method, called OBSM, was recently proposed which employs overcomplete basis functions to achieve sparse representations. While the method can handle non-stationary response without the… (More)
